Simple request and respone example using rest assured.

        //In any rest assured program we first define baseURl ,port and basePAth
        RestAssured.baseURI = "http://localhost";
        RestAssured.port = 8080;
        RestAssured.basePath = "/student/list";
        
        //Then we make a req object . to make a given object need to import RestAssured.given class
        //import static io.restassured.RestAssured.given;



        RequestSpecification req  = given();
        
        //Then we can define content type for that req
        req = req.contentType(ContentType.JSON);
        
        //Then we can add headers
        req = req.header("X","Y");
        
        //logging-We can log the req to see how our request actually looks like
        req = req.log().all();
        
       //Then we create a response object that gets the response from the get method we applied on our req object.
        Response response = req.get();
         //Then from response object we can get contentType , headers , response code etc.
    //Getting the content type
      System.out.println(response.getContentType());
       //Getting the header
      System.out.println(response.getHeaders());
       //Getting the time
      System.out.println(response.getTime());
      //Getting the status code
      System.out.println(response.getStatusCode());
     //print the entire response    
     response.print();
      //Or we can print the response in a nice format.
     response.prettyPrint();
   }
